News of McGahn's departure from the White House was first reported by The New York Times, which cited two people close to him. Two White House officials confirmed to NBC News that Wednesday was McGahn's last day.

McGahn's departure comes a day after President Donald Trump told The Associated Press in a Tuesday interview that Washington lawyer Pat Cipollone would serve as his next White House counsel.

Trump in August said McGahn would leave the White House in the fall.
